Job description
🚀 AI/ML Engineer (Applied AI - Government & Enterprise)
Location: Hybrid 3 days/week on-site in San Francisco or NYC
Compensation: $200,000 – $350,000 Base Salary + Competitive Equity
Visa Status: Open to US Visa Transfers (OPT, H-1B, etc.)
🌟 The Company
Our client is an elite, high-growth applied AI startup ($55M Series A backed by top-tier tech leaders including Andrej Karpathy, Patrick Collison, and Elad Gil).
In less than two years, they have grown to over 140 employees and hit $20M+ in revenue by deploying production-grade AI systems directly into high-stakes environments—automating complex, real-world workflows for international governments, healthcare systems, and Fortune 500 energy leaders.
💡 The Role
This is an applied, product-driven AI engineering role. You will bridge the gap between cutting-edge LLM research and real-world deployment, building AI agents, reasoning systems, and complex data pipelines that solve critical, manual problems globally.
You will own projects end-to-end—from post-training and prompt engineering down to production code and direct engagement with government officials and enterprise leaders.
🎯 Key Responsibilities
- Design & Deploy: Build and ship advanced LLM architectures, AI agents, and RAG systems into production environments for global nation-states and enterprise clients.
- Optimize & Scale: Build scalable data pipelines, design robust ML eval frameworks, and optimize models for real-world reliability and accuracy.
- Direct Engagement: Interact directly with customer leadership and government stakeholders to understand domain challenges and deliver custom AI solutions.
- Full-Stack Impact: Wear multiple hats across software engineering, product direction, and customer engagement in a high-velocity startup setting.
💻 Tech Stack
- Languages & Frameworks: Python, PyTorch, JAX, TensorFlow
- AI/ML Architecture: LLMs, RAG, AI Agents, Reasoning Models, Data Pipelines
- Eval & Testing: Modern ML Evaluation Frameworks, CoderPad
🛠️ What We're Looking For
- 3 – 10 Years Experience: Applied, product-focused AI/ML engineering background (building production applications in Python).
- Applied Product Focus: Hands-on experience deploying LLMs, RAG, or AI agents to external end-users (this is NOT a pure research, MLOps, or platform infra role).
- Proven Business Impact: Ability to clearly articulate and quantify the commercial or operational impact of your ML systems (e.g., revenue generated, time saved, accuracy gains).
- Startup Credential: Experience in high-velocity startup environments (e.g., Glean, Cohere, Together AI, Databricks) or fast-paced product teams at select tech firms (e.g., DoorDash, Amazon, TikTok, Stripe). Ex-founders and founding engineers are highly valued.
- Education: BSc/MSc in Computer Science (top CS programs preferred for junior/mid-level profiles).
🔴 Red Flags / Out of Scope
- Purely research-heavy or PhD-focused profiles with no product/production shipping experience.
- MLOps, platform, or infrastructure-only engineers.
- Candidates exclusively from traditional corporate/legacy engineering cultures (e.g., Oracle, Salesforce, big banks).
🎁 Why Join
- Explosive Growth: Joined a 140-person team that hit $20M+ revenue in year one.
- Elite Backing: Backed by legendary Silicon Valley founders and investors ($55M Series A).
- Real-World Footprint: Your code directly powers critical government, energy, and healthcare infrastructure globally.
- End-to-End Autonomy: High accountability, zero bureaucracy, and high-impact equity.
🧩 Interview Process
- Recruiter Screen (30 mins): High-level screen with the internal team assessing background, startup velocity fit, communication skills, and project impact.
- ML Technical Interview (60 mins): Real-world ML problem-solving session testing how you translate a business scenario into an ML problem, define evaluation metrics, and architect the solution.
- Live Coding Interview (60 mins): Virtual CoderPad session testing Python fundamentals, debugging, and practical engineering skills (applied, non-Leetcode style problem; AI tools allowed).
- Onsite Interview (3.5 Hours):
- Two technical screen rounds
- Past project deep-dive with an Engineering Manager (evaluating startup pace, technical depth, and cross-functional collaboration)
- Lunch, office tour, and culture alignment chat with the team
Visa sponsorship record
No public sponsorship records foundWe didn't find H-1B, H-1B1, E-3 or green card (PERM) filings under the name Protech Talent in the Department of Labor and USCIS data. That doesn't mean the job can't be sponsored — the company may file under a different legal name, be new to sponsorship, or sponsor a visa that isn't in these datasets (for example H-2B or J-1).
Tip: ask the recruiter early, in writing, which visa they sponsor and whether they cover the legal and filing fees.
Which visas can work for this job
Occupation: Software Developers (SOC 15-1252).
- Mentioned in the listing
H-1B, OPT
- H-1B cap-exempt employer
Regular cap-subject employer — a new H-1B needs to win the lottery in March (unless you already hold cap-counted H-1B status).
- TN (citizens of Canada and Mexico)
This kind of role may fit the USMCA profession “Computer Systems Analyst (or Engineer, for engineering-degree holders)” — it depends on the actual duties. No lottery, no cap; you need the matching degree or license.
- E-3 (Australia) and H-1B1 (Chile, Singapore)
Same degree requirement as H-1B, but no lottery and a separate quota that is rarely filled.
- O-1 (extraordinary ability)
For candidates with awards, publications, press, a high salary or critical roles at distinguished organizations. No cap, no lottery; the employer files a petition.
- STEM OPT extension (F-1 students)
Requires an E-Verify employer. We didn't find this company in the E-Verify list — ask HR.
Salary vs prevailing wage
Level IV (fully competent)Software Developers · United States (national median of areas). Annual prevailing wages set by the Department of Labor (OFLC).
| Level | Prevailing wage | H-1B lottery odds* |
|---|---|---|
| Level I | $79,290 | ~15% |
| Level II | $100,152 | ~31% |
| Level III | $120,422 | ~46% |
| Level IV | $141,190 | ~61% |
This job pays $200,000–$350,000 a year — that's Level IV (fully competent). In the wage-weighted H-1B lottery a Level IV registration gets 4 entries; estimated selection chance about 61% — better than average.
* Odds are DHS projections for the FY2027 wage-weighted lottery (actual results vary by year and employer). Since the FY2027 cap season the H-1B lottery is weighted by wage level: Level I = 1 entry, II = 2, III = 3, IV = 4. The level is set by the offered wage against the prevailing wage for the occupation and worksite. Separately, a $100,000 fee for new H-1B petitions for workers outside the US was announced in 2025; as of September 2026 a federal court ruling keeps it unenforceable while appeals continue — check the current status.
